I'm researching GTX 570s for a rig that I'm building, and they all seem to be somewhere in the range of £200 - apart from one, which is more around £160. Too good to be true? I't s reputable eBay seller, with free delivery. I can't find any discrepancy amongst the specifications, apart from the fact that it claims to be 'manufacturer refurbished', and it doesn't mention memory clock - it only mentions RAMDAC speed, which is at 400Mhz. It also mentions needing a power supply of above 650W, with at least one 8-pin and 6-pin external connector.
